Abstract

According to the most recent Commonwealth Fund Affordable Care Act Tracking Survey, March–May 2015, an estimated 25 million adults remain uninsured. To achieve the Affordable Care Act’s goal of near-universal coverage, policymakers must understand why some people are enrolling in the law’s marketplace plans or in Medicaid coverage and why others are not. This analysis of the survey finds that affordability—whether real or perceived—is playing a significant role in adults’ choice of marketplace plans and the decision whether to enroll at all. People who have gained coverage report significantly more positive experiences shopping for health plans than do those who did not enroll. Getting personal assistance—from telephone hotlines, navigators, and insurance brokers, among other sources—appears to make a critical difference in whether people gain health insurance.

BACKGROUND

The third open enrollment period for the Affordable Care Act’s health insurance marketplaces begins on November 1, 2015, for coverage beginning January 2016. This will give the estimated 25 million working-age adults who still lack health insurance and are eligible for coverage the opportunity to sign up.1 In addition, people who currently have insurance—either through the marketplaces or the individual market—will need to reenroll during this period if they want their coverage to continue through next year.
Some people, however, may choose not to enroll in coverage. To help policymakers increase the number of people with health insurance, it’s important to understand why some people have enrolled while others have not. Earlier research, based on results from the Commonwealth Fund Affordable Care Act Tracking Survey, March–May 2015, identified possible reasons why people remain uninsured, including the fact that 20 states have yet to expand eligibility for Medicaid and a general lack of knowledge among many uninsured adults about the marketplaces and the availability of financial assistance.2 In this latest analysis of the survey, we gain more insight by looking at the experiences of adults who took the first steps toward gaining coverage by visiting the marketplaces but who did not ultimately enroll. Additional findings from the survey can be found in an online tool.

SURVEY FINDINGS

Visiting the Health Insurance Marketplaces and Shopping for Coverage

One-quarter of all U.S. working-age adults had visited a marketplace to shop for health insurance by March–May 2015; even higher rates were reported by young adults and people with low and moderate incomes (Exhibit 1). The share of Latinos who visited the marketplaces climbed significantly over the first two enrollment periods, rising from 19 percent to 27 percent.
Nearly half (47%) of adults who went to the marketplaces and shopped for health insurance over the past two years ultimately enrolled in plans: 30 percent said they selected a private health plan, 15 percent enrolled in Medicaid, and 2 percent either did not know their coverage type or refused to respond (Exhibit 2).3

Despite concerns that young adults might not sign up for the law’s coverage options, 19-to-34-year-olds comprise more than one-third (38%) of the current combined enrollment in marketplace and Medicaid plans among working-age adults (Exhibit 3). Young adults represent 31 percent of adult enrollees in the marketplaces, proportionate to their share of the adult population.4 Medicaid has been a critical source of new insurance coverage in this age group: 46 percent of new adult Medicaid enrollees are ages 19 to 34.

Making the Decision to Enroll

In this analysis, we examine the decision-making of people who enrolled in marketplace plans or Medicaid compared with those who did not enroll. Going forward we refer to these two groups “enrollees” and “nonenrollees.”

Enrollees

Premiums and out-of-pocket costs figured most prominently in decisions regarding choice of marketplace plan. Two-thirds (66%) of adults who either had enrolled in private plans through the marketplace for the first time or switched health plans in the most recent open enrollment period said that the amount of the premium (41%) or the amount of the deductible and copayments (25%) was the most important factor in their decision (Exhibit 4). A smaller share of adults (22%) said that having their preferred doctor, health clinic, or hospital included in the plan’s network was the most important reason. In a companion issue brief, we examine reported premium costs and deductibles by adults with marketplace plans.

Consistent with these findings, many adults opted for a limited network of doctors and hospitals in exchange for lower premiums. Among people who either enrolled in a marketplace plan for the first time or changed plans in the most recent open enrollment period, more than half (53%) said they had the option of choosing a less expensive plan featuring fewer doctors or hospitals (Exhibit 5). Of those, more than half (54%) selected the limited-network plan.

Nonenrollees

We asked adults who had visited the marketplaces but did not enroll in a marketplace plan or Medicaid about their reasons for not enrolling; respondents could select more than one response.
Half (51%) of nonenrollees said they did not enroll because they ultimately found health insurance through another source (Exhibit 6). These may have been people with changes in life circumstances such as a job loss or divorce, who shopped for insurance but ended up getting covered in another way.

Affordability was a key reason people did not enroll in plans. More than half (57%) of adults who visited the marketplaces but did not enroll said they could not find a plan they could afford. Excluding the adults who also said they gained coverage elsewhere,5 the majority of those who did not enroll because they couldn’t find affordable plans had lower incomes. More than half (54%) had incomes in the range that made them eligible for subsidies (i.e., from 100 percent to 400 percent of the federal poverty level, or $11,670 to $46,680 in annual income for an individual) (data not shown).6 Thirty percent had incomes under 100 percent of poverty. An estimated 26 percent (and thus nearly all of those with incomes under 100 percent of poverty) were likely in the so-called Medicaid coverage gap. That is, they were living in states that had not expanded eligibility for Medicaid at the time of the survey and had incomes under 100 percent of poverty and thereby not eligible for marketplace subsidies.7 About 11 percent had incomes that exceeded the threshold that made them eligible for subsidies (i.e., 400 percent of poverty).

Many adults (43%) said they did not enroll because they were not eligible for subsidized coverage or Medicaid. Again, excluding those who gained coverage elsewhere,8 most people who gave this reason had lower incomes: 50 percent had incomes that made them eligible for subsidies, and 33 percent had incomes under 100 percent of poverty (data not shown).9 An estimated 27 percent—most of those with incomes under 100 percent of poverty—were likely in the Medicaid coverage gap. About 14 percent had incomes above the threshold that made them eligible for subsidies.10

Other adults who did not enroll were overwhelmed by the process. About four of 10 adults (38%) who did not sign up for coverage said they found the process of enrolling difficult or confusing.11

Shopping and Enrollment Experiences

We compared the shopping and enrollment experiences of enrollees and nonenrollees. In the analysis we excluded those who told us they had enrolled in another source of coverage from the group of nonenrollees.

Personal Assistance

Receiving personal assistance appears to make a significant difference in whether a person signs up for coverage. People with incomes in the range that made them eligible for subsidies, those who are part of racial and ethnic minority groups, those with a high school education or less, and older adults were the most likely to report they had received personal assistance such as from a telephone hotline, insurance broker, navigator, or some other source (Appendix Table 1). When we controlled for demographic differences, 78 percent of adults who said they had received assistance enrolled in a marketplace plan or Medicaid (Exhibit 7).12 In contrast, only 56 percent of those who did not receive personal assistance ultimately enrolled.

Comparing Health Plans

Visitors to marketplace websites in most states encounter an array of health plans that differ by premium cost, copayments and deductibles, and covered providers.13 Health care services covered by plans should be largely the same because each must cover the same essential health benefits, as required by the law. We asked people who visited the marketplaces how difficult or easy it was to compare health plans on the basis of premium costs, benefits covered, out-of-pocket costs, and provider networks.14 Looking only at adults who had incomes above the threshold that made them eligible for marketplace plan subsidies, those who enrolled were significantly more likely than those who did not to report an easy time identifying differences among plans on those dimensions (Exhibit 8).15

Finding an Affordable Plan

Adults who enrolled in marketplace plans were significantly more likely to report they had an easy time finding an affordable health plan than those who did not enroll (Exhibit 9). Fifty-seven percent of adults who enrolled in marketplace plans said it was very or somewhat easy to find a plan they could afford compared with 15 percent of those who did not enroll. Marketplace enrollees were also significantly more likely to report relative ease in finding plans with the type of coverage they needed than those who did not enroll (63% v. 36%).16

Overall Shopping Experience

People who ultimately enrolled in either Medicaid or a marketplace plan were significantly more likely than those who did not to give high ratings to their overall experience. More than half (52%) of adults who obtained coverage rated their experience as good or excellent compared with 18 percent of those who did not enroll (Exhibit 10).17

CONCLUSION

The survey findings suggest strategies policymakers might pursue to continue to reduce the number of Americans who lack health insurance.

Affordability was a primary reason nearly 50 million Americans lacked health insurance before the Affordable Care Act and it clearly remains a top concern for people seeking coverage today.18 One startling finding is the fact that among those adults who said they did not enroll because they could not find an affordable plan and did not enroll through a different source, more than half (54%) had incomes that made them eligible for subsidies. It is unclear whether the subsidies are insufficient across income levels to help all those eligible enroll or whether there is a lack of clear information about the subsidy assistance and the actual net costs of insurance to potential enrollees.

The implications of this latter problem—that many people may not have the information they need to help them buy coverage on their own—are evident throughout the survey findings. For example, compared with people who enrolled, those who did not ultimately enroll had much greater difficulty comparing plans based on premium costs, potential out-of-pocket costs, provider network, and benefits covered.

The findings also suggest that getting assistance during the enrollment process may have helped people better understand the trade-offs between their health plan choices. We find that receiving personal assistance or not during the enrollment process made a significant difference in whether people signed up for coverage. Other recent research also has found that navigators and other types of assisters are powerful predictors of successful enrollment.19

Finally, the decision by 20 states not to expand eligibility for Medicaid is keeping people from gaining coverage. More than a quarter (26%) of adults who shopped for health insurance in the marketplaces and cited affordability as a reason for not enrolling likely fell into the Medicaid coverage gap. For low-income adults in these 20 states, the inability to afford health insurance remains a reality.

How This Survey Was Conducted

The Commonwealth Fund Affordable Care Act Tracking Survey, March–May 2015, was conducted by SSRS from March 9, 2015, to May 3, 2015. The survey consisted of 16-minute telephone interviews in English or Spanish and was conducted among a random, nationally representative sample of 4,881 adults, ages 19 to 64, living in the United States. Overall, 2,203 interviews were conducted on landline telephones and 2,678 interviews on cellular phones, including 1,729 with respondents who lived in households with no landline telephone access. The survey questionnaire is available.

This survey is the third in a series of Commonwealth Fund surveys to track the implementation and effects of the Affordable Care Act. The first was conducted by SSRS from July 15 to September 8, 2013, by telephone among a random, nationally representative U.S. sample of 6,132 adults ages 19 to 64. The survey had an overall margin of sampling error of +/– 1.8 percent at the 95 percent confidence level.

The second survey in the series was conducted by SSRS from April 9 to June 2, 2014, by telephone among a random, nationally representative U.S. sample of 4,425 adults ages 19 to 64. The survey had an overall margin of sampling error of +/– 2.1 percent at the 95 percent confidence level. The sample for the April–June 2014 survey was designed to increase the likelihood of surveying respondents who were most likely eligible for new coverage options under the ACA. As such, respondents in the July–September 2013 survey who said they were uninsured or had individual coverage were asked if they could be recontacted for the April–June 2014 survey. SSRS also recontacted households reached through their omnibus survey of adults who were uninsured or had individual coverage prior to the first open enrollment period for 2014 marketplace coverage.

The March–May 2015 sample also was designed to increase the likelihood of surveying respondents who had gained coverage under the ACA. SSRS also recontacted households reached through their omnibus survey of adults between November 5, 2014, and February 1, 2015, who were uninsured, had individual coverage, had a marketplace plan, or had public insurance. These households were then recontacted for the March–May 2015 survey. All waves of the survey oversampled adults with incomes under 250 percent of poverty to further increase the likelihood of surveying respondents eligible for the coverage options as well as allow separate analyses of responses of low-income households. The measure used to designate insurance type was modified in 2015 using new follow-up questions that were asked of those adults who reported having more than one type of coverage.

The data are weighted to correct for the stratified sample design, the use of recontacted respondents from the omnibus survey, the overlapping landline and cellular phone sample frames, and disproportionate nonresponse that might bias results. The data are weighted to the U.S. 19-to-64 adult population by age, gender, race/ethnicity, education, household size, geographic division, and population density using the U.S. Census Bureau’s 2013 American Community Survey and weighted by household telephone use using the U.S. Centers for Disease Control and Prevention’s 2014 National Health Interview Survey.

The resulting weighted sample is representative of the approximately 187.8 million U.S. adults ages 19 to 64. Data for income, and subsequently for federal poverty level, were imputed for cases with missing data, utilizing a standard regression imputation procedure. The survey has an overall margin of sampling error of +/– 2.1 percentage points at the 95 percent confidence level. The landline portion of the main-sample survey achieved a 16.9 percent response rate and the cellular phone main-sample component achieved a 13.3 percent response rate. The overall response rate, including the recontacted sample, was 12.8 percent.

2 At the time the survey was conducted, 22 states had not yet expanded eligibility for their Medicaid programs. Since the survey, two states (Alaska and Montana) have moved forward with plans to expand eligibility. Collins, Rasmussen, Doty, and Beutel, Americans’ Experiences with Marketplace and Medicaid Coverage, 2015.

3 About 1 percent of adults who visited said they enrolled but did not know what type of coverage they had.

5 Of the group who said they did not enroll because they couldn’t find an affordable plan, 38 percent said they found coverage through a different source (data not shown). The sample size for this analysis was 290.

6 Breaking this down further, 39 percent had incomes that made them eligible for the most generous subsidies (100%–249% of poverty) and 15 percent had incomes between 250 percent and 399 percent of poverty (data not shown).

7 It is possible that some adults in this income range may have been eligible for coverage under their state’s existing Medicaid program.

8 Of those who didn’t think they were eligible for subsidized coverage or Medicaid, 40 percent found coverage through a different source (data not shown). The sample size for this analysis was 231.

9 Thirty-four percent had incomes between 100 percent and 249 percent of poverty and 16 percent had incomes between 250 percent and 399 percent of poverty.

10 Undocumented immigrants are not eligible for either the law’s Medicaid expansion or marketplace plans. While we do not ask specifically about immigration status in the survey, among those who did not sign up because they said they were ineligible for financial assistance, 14 percent indicate that they were born outside of the United States. However, this measure most likely overstates the number of people who were not eligible because of their immigration status.

11 Forty-one percent of those who found the process difficult or confusing said they found coverage through a different source (data not shown).

12 Adjusted percentages were estimated based on a logistic regression model that controlled for race, education, poverty, age, and health status.

15 Looking at the full group of visitors to the marketplace, a higher level of education did not appear to make a significant difference in whether people reported that it was very or somewhat easy to compare health plans on these four dimensions.

18 In 2013, 66 percent of the under-65 uninsured population earned less than 200 percent of poverty, or $23,000 for an individual and $47,000 for a family of four.
